Ferulok 24 Flareless Fittings | #4 PNU-S

Parker’s 24° Flareless tube fittings, Ferulok, have a visible bite which allows the fitting assembler to visually inspect the bite quality, which significantly minimizes the risk of improper assembly and related service problems in hydraulic connections. The rear compression grip of the ferrule firmly holds the nut and tubing, dampening the effects of vibration and extending the life of the joint. Exceeding the requirements of SAE J514, Ferulok Flareless fittings are especially suitable for use with applications requiring tube wall thicknesses ranging from medium to extra heavy.

Markets:

• R & D
• Lubrication
• Power Plants
• Off-Shore Oil & Gas
• Compressor
• Military Ground Systems
• Machine Tool

Features/benefits:

• Offered in steel and stainless steel in sizes: 1/8″ through 2″ with working pressures up to 6000 psi.
• Stainless Steel nuts have a coating to prevent galling.
• No special tooling is required for smaller sizes of Ferulok which can be assembled by wrench for sizes up to 3/4″.
• Steel fittings substantially exceeded the SAE corrosion requirements of 72 hours without red rust, lasting up to 1,000 as found by an independent test facility.  This enhanced performance provides customers with a competitive advantage through extended equipment life, leading to increased revenues and reduced warranty costs.
• Parker’s Robust Port Stud on adjustable ports is manufactured with a longer locknut virtually eliminating washer damage and potential leaks, as well as making assembly virtually mistake-proof. This feature improves customer internal efficiencies and reduces rework costs resulting from backup washer damage commonly seen with traditional SAE adjustable port ends in the market.
• Metal-to-metal sealing makes it suitable for a broad range of temperature and media types.
• Especially suitable for use with tube wall thickness ranging from medium to heavy
• Compression grip at rear of ferrule dampens the effects of vibration which extends the life of the joint in rigorous applications.
• Hardened ferrule creates a visible heavy bite so no inspecting gauges are required.

Applications

• Hydraulic fluid and gas handling connections
